A a wire, a wire is connected between the positive and negative ends of the eletrical energy source and connects all the components in between.
Global warming, acid rain and general air pollution from car exhaust occurs from burning fossil fuels. The global warming occurs because of a "green house effect" where sunlight is trapped inside our atmosphere due to air pollution. Acid rain occurs when the products of combustion, sulfur dioxide, nitrous dioxide and nitrogen dioxide mix with rain water.
Each of these impacts is very extensive. Each fossil fuel has individual impacts related to their use
Answer:
mass, volume: quantitative propereties: extensive properties
volume, melting point: quantitative propereties: intensive properties
Explanation:
The quantitative properties of matter are characteristics of matter that can be measured and of which quantities can be expressed.
Quantitative properties can be divided into 2 groups:
- Extensive properties: This is whose value depends on the amount of substance analyzed. They are not properties that allow us to distinguish one substance from another, since its value changes depending on the size of the object or sample that you have.
- Intensive properties: are those that do not depend on the mass or size of a body. That is, these are properties whose value is independent of the amount of substance analyzed; they are useful for differentiating substances.
On the other hand, the qualitative properties of matter are those that cannot be expressed in numerical values or quantities. They are detected, in many cases, through the senses, since they do not measure them.
In this case:
- <u><em>mass, volume: quantitative propereties: extensive properties</em></u>
- <u><em>volume, melting point: quantitative propereties: intensive properties</em></u>
